Abstract
This paper traces the historical perspective based on Germany’s experiences with mechanical and biological treatment (MBT), introducing this technology from the pretreatment processes before landfilling for resource recovery. The applicability of MBT for waste management systems in Japan is also discussed. MBT is considered to be a generic process, in which element technologies, such as shredding, separation, aerobic composting and anaerobic digestion, are integrated as a system. This is done according to certain objectives that include minimization of landfilled waste and maximization of resource recovery. MBT is not to be considered an alternative to the incineration process, but to be carried out in collaboration with incineration. In thinking of future waste management systems for Japan, which must address the issues of waste reduction and changes in waste qualities due to population decrease and promotion of recycling, MBT can provide beneficial opportunities in the reconsideration of Japan’s waste management systems, especially with regard to recovery of resources and energy.
